Soft washing is the process of applying a low-pressure mix of soaps and biodegradable chemicals to clean exterior surfaces. Soft washing relies on the viability of the chemical to do the cleaning as opposed to a high pressure power wash. Power washing increases the likelihood of damaging exterior surfaces, and therefore, softwashing is appropriate in places where power washing is not ideal. We apply a powerful, biodegradable chemical to safely kill all the mold, mildew, algae, and underlying bacteria causing those black streaks. Soft Washing is safe and effective for virtually any roof or surface on a house, office building, school, hospital, industrial or multi-family housing. We can safely clean concrete, brick, flagstone, travertine, marble, slate, limestone, cast stone, aluminum, vinyl siding, shingles, wood, stucco, EIFS, Dryvit, and much more!
